None of the above makes up for losing out on some of the best games ever. And lets face it... its about the games. Not your processor or graphics chip.
Oh, one thing... cheaper games? Can you rent PC games?
There are VERY few games that were worth playing that didn't make it to PC. And it is nice to play a game like battlefield 3 at 60 fps which the xbox360 was not getting.
But how many exclusives were really that amazing that didn't come to pc that are consider some of the best ever? Red Dead? It was ok at best. Just a wild wild west GTA.
